I have a Centos 5.4 machine that has, for the past two weeks, apparently been shut off over the weekend. It's just sitting there turned off on Monday morning and when someone hits the power switch it comes right back on and everything works again.
This happened last weekend, and again over this past weekend.
Here is /var/log/messages from shortly before it apparently shut down this weekend. Can anyone tell me what is or might be going on?
